During the last week the observing schedule was replanned to include a
series of observations of the Crab Nebula that was accepted as a
Target of Opportunity on Apr 12. The replanned loads were uplinked on
Apr 13. Planned observations of IGR J15415-5029, SLJ1647.7+3455, and
NGC 7008 were impacted and will be rescheduled at a later date.

Real-time procedures were executed on Apr 14 in preparation for the
start of the 2011 spring eclipse season: one to activate SCS 29 and
one to dump and clear the EPS glitch counters. An additional real-time
procedure was executed on Apr 14 to perform a diagnostic dump of the
Central Processing Electronics (CPE). Chandra passed through the first
eclipse of the season on Apr 15 with initial indications of nominal
power and thermal performance.

A Chandra image release was issued on Apr 13 describing a search for
the Milky Way's most massive stars, using data from Chandra and
Spitzer. Dust and gas obscure much of the view of the plane of our
Galaxy from optical telescopes. X-rays can penetrate this veil and
help astronomers study these giant stars. For details see:

The schedule of targets for the next week is shown below and includes
one of the series of the Crab Nebula Target of Opportunity
observations, observations of FK Com coordinated with the HST, and an
observation of MAXIJ1659-152 coordinated with the EVLA.
